Out of curiosity, has anyone tried running Windows 7 on their MacBook Pros via an ExpressCard/34 SSD, or know anything about it? I know people can and do boot into OSX with zero problems from ExpressCard/34 SSDs, but so far I don't know if anyone has done so successfully with Windows, much less Bootcamped Windows.

If you have, or know of someone who does, any idea if they had to do anything special to make it run? Know of any brands that work better than others? I'd just get one and try it myself, but they're a bit expensive to just buy and then experiment with.

I'm not really up to speed on the wizardry needed to get Boot Camp working anymore, but I've booted into backups of OSX via expresscard to an eSATA HDD before... It was just a crummy cheap expresscard thing I got, but it generally works OK via OSX's built in drivers.

If you want reliability, Sonnettech are probably the most compatible and tested on that front, and then see if you can install Boot Camp to and boot from an external eSATA drive. If that works, then I don't see why an expresscard SSD wouldn't.

I know FireWire drives work with Boot Camp as long as you install to a partition on your internal drive first and then clone it with WinClone or something like that to the FireWire drive, so I'd assume eSATA would be just as easy. But, that's still using an external drive.

I know there are EC/34 SSDs up to at least 128GB out there, so my main interest is in being able to keep my Boot Camp partition on a little EC/34 SSD that I can just plug into the computer and use rather than lugging around an external drive with power supply, cabling, etc. Not to mention something plugged into the PCI bus should be a lot faster than running off a FireWire cable.

Egh, too expensive for too little space, despite the speed and not adding any excess bulk. I might still try this out later, but decided to just go with a 2TB Western Digital MyPassport Studio drive for now. Plenty of space so I can partition it for other stuff as well, compact, and most importantly bus-powered off of FireWire 800.
